2.77b Thermoregulation

• Hyperthalamis is a region of the brain which responds to the stimuli (temperature of blood)
• Temperature is the stimuli, hyperthlamis is the receptor, skin activity is the responce
• If temperature is too warm, the response of the skin would be sweating, vasoliation and hairs flat
• If temperature is too cold, the response of the skin would be shivering, hair raised and vasoconstriction
• Homeothermic carries out a process called Thermoregulation.
• Mammals body temperature is 37 to 38 degrees celcius
